Detects instances where 'node.exe' is copying browser history SQLite databases (Chrome, Edge, Brave) to temporary directories, potentially indicating data exfiltration or staging. This behavior has been observed in supply chain attacks like the 'easy-day-js' incident involving the 'protocal.cjs' backdoor.
Detects instances where 'node.exe' is copying browser history SQLite databases (Chrome, Edge, Brave) to temporary directories, potentially indicating data exfiltration or staging. This behavior has been observed in supply chain attacks like the 'easy-day-js' incident involving the 'protocal.cjs' backdoor.
Detects Node.js or JavaScript runtimes executing code patterns commonly associated with GlassWorm-style supply chain attacks. The campaign abuses invisible Unicode variation selectors to hide malicious payloads that are decoded and executed through eval(). Investigate execution originating from repositories, package managers, VS Code extensions, or temporary development directories.
Detects the creation or modification of '.env' files within '.gemini' directories, often found in CI/CD pipelines or developer environments. This activity may indicate an attempt to inject malicious environment variables to hijack the execution flow of the Gemini CLI or related tooling.
Detects Content Security Policy (CSP) violation reports or network traffic containing references to 'netdna-ssl.com' or 'netdna-cdn.com'. These hostnames are legacy CDN domains that have been re-registered, presenting a significant supply chain risk where malicious content could be injected into web applications loading resources from these domains.
This rule detects the creation or modification of generic executable files (e.g., 'me.exe', 'update.exe') within the Hola installation directory. It specifically looks for executables whose names match common updater or service patterns and whose process command line includes 'hola', 'update', or 'installer'. This activity could indicate a compromised delivery pipeline or supply chain attack, as observed with the Hola browser.
Detects DNS queries and network connections to 'netdna-ssl.com' and its subdomains, as well as specific IP addresses (104.21.72.58, 172.67.175.240) associated with the re-registered domain. This domain was re-registered by a third party in July 2025 and now resolves legacy WP Engine CDN hostnames, creating a potential supply chain risk.
Detects node.exe spawning powershell.exe as a child process, consistent with malicious npm postinstall lifecycle hooks used by the PostCSS typosquatting campaign (postcss-minify-selector-parser / postcss-minify-selector). The attack chain decrypts an AES-256-GCM blob at runtime and executes a PowerShell downloader stage.
Detects instances where 'node.exe' is copying browser history SQLite databases (Chrome, Edge, Brave) to temporary directories. This activity is associated with the 'protocal.cjs' backdoor from the easy-day-js supply chain attack, which aims to exfiltrate sensitive browser data.
Detects instances where 'node.exe' is copying browser history SQLite databases (Chrome, Edge, Brave) to temporary directories, potentially indicating data exfiltration or staging. This behavior has been observed in supply chain attacks like the 'easy-day-js' incident involving the 'protocal.cjs' backdoor.
Detects command lines that reference known supply chain attack targets or commonly used package management tools like npm and pypi, which can be indicators of supply chain compromise.
Detects the execution of processes with command-line arguments containing keywords related to known supply chain attacks (e.g., solarwinds, 3cx, kaseya, npm, pypi). This rule is intended for threat hunting to identify potential exploitation attempts or malicious activity involving software supply chain components.
This rule detects the dropping of a 24-character hexadecimal JavaScript payload followed by the creation of a '.pkg_history' or '.pkg_logs' marker file within a one-minute timeframe. This behavior is indicative of the Mastra NPM supply chain compromise.
Detects npm.cmd or npx.cmd directly spawning the bun.exe payload runtime, which could indicate a supply chain attack or malicious package execution.
This rule detects an unusually high volume of operations related to GitHub Enterprise repositories, such as adding users, creating teams, pushing to repositories, or changing permissions, within a short timeframe. This could indicate a compromised account or automated malicious activity targeting source code repositories.
Detects HTTP GET requests for JavaScript or CSS resources from netdna-ssl.com or wpengine.netdna-ssl.com subdomains. This activity could indicate a supply chain compromise where malicious code is injected into legitimate web resources served from these content delivery networks.
Identifies web server processes initiating network connections to the credential-stealing generate.2faplugin.org domain. This activity is indicative of a supply chain compromise targeting ShapedPlugin, where backdoored pro plugins are distributed via official channels, leading to data exfiltration.
This rule identifies newly created PHP files within specific WordPress plugin folders ("woocommerce-subscription" or "woocommerce-notification") that have a rare SHA256 hash count (less than 5 occurrences in the enterprise). This behavior is indicative of web shells or backdoored plugin files, potentially introduced via a supply chain compromise.
This rule detects the execution of JavaScript files named 'bw_setup.js' or 'execution.js' using the 'bun' runtime, immediately followed by an outbound network connection to the command and control (C2) domain 't.m-kosche.com'. The detection logic correlates process execution events with network connection events within a 10-minute window, indicating potential malicious activity associated with supply chain attacks.
This rule detects an unusually high volume of operations related to GitHub Enterprise repositories, such as adding users, creating teams, pushing to repositories, or changing permissions, within a short timeframe. This could indicate a compromised account or automated malicious activity targeting source code repositories.
Detects suspicious NPM package installations that may indicate typosquatting or supply chain compromise attempts. The rule looks for `npm install` or `npm add` commands with package names containing special characters (@, ^, ~) and common prefixes used in typosquatting (typosquatting-, common-, util-), while excluding 'json' to reduce false positives. A high count of such installations within an hour from a single user and computer is flagged.
